BCS GAC Demonstration

Brennan has revolutionized sediment capping possibilities with its newly patented Broadcast Capping System (BCS™). This system uses the principles of hydraulic transport to deliver clean sand and granulated activated carbon to a distribution barge where it is rapidly dewatered and unobtrusively spread over the bottom of the waterway. Brennan’s sediment capping system can accurately place materials up to 3 inches in diameter, while achieving a homogenous thickness with even distribution.
